How to get NR to default to zero

Permanently deleted user
This has been a reoccurring problem that I can't figure out.

Basically I never want C1's Noise Reduction to be invoked. It smears colors especially in high ISO images and I'd rather use other tools for NR.

At one time I thought the NR settings had defaulted to zero for both Luminance and Color, but now even after I pull the slider to zero and save it as a new default, as soon as I go to the next frame, the NR has jumped back up to where it was before.

I shouldn't have to Select All and apply a zero NR to all selections, should I?

I've gone through the entire manual but found nothing regardin this.

Thanks in advance,

Peter

    Well, I tried this at home...
    CO 4.6.2, OS X 10.5.6, Leica M8 DNG

    Default NR Lum=25; Clr=40. Set both to zero on one image. Save as Defaults. Move to next or previous image. Each image that had the previous defaults (25/40) now has the new defaults (0/0). Each image that had value adjusted now has still that value.

    Is this behavior different from yours? Which version, which raw file type are you using?

    Hi paul!

    Thanx for your care and always helpfull comments.
    I tried the same as you suggested, and indeed all the new default values are 0/0.
    BUT there is still noise reduction aplied to the image despite the values showing 0/0.
    So one has to move the sliders a little up and down to actually have zero NR.
    This definitly seems to be another bug.
    I´m no native speaker, so I hope I could make myself clear.

    greetings wolfger

    P.S.: I think this behaviour already was mentioned in a different post

    I was on an earlier version - 4.5.2 - I think. I downloaded the latest 4.6.2 yesterday and was dismayed to find that the system requirements have changed so I also had to upgrade from 10.5.5 to 10.5.6 on a MacPro 2.8.

    While the new version did indeed "hold" the new default settings, I also experienced the exact same behavior as the previous poster. Yes, even though the NR indicated a zero input, it was in fact applying some degree of NR. As with the previous poster, it took moving the sliders away from zero and back again to insure no NR.

    This is the kind of thing you don't even think you have to check and has already caused me to have to re-process a heap of images. Who woulda thunk the sliders weren't working as advertised.

    Anyhow, if it were up to me, I'd put the fix on a fast track.

    this happens to me too on a brand new 24" imac, very annoying. With both sharpening and noise reduction I set the defaults to be how I want them but all that changes in subsequent images or sessions is that the sliders show my new defaults but the images still reflects the old settings until I move the sliders slightly. Also I can't copy and paste ICC profile settings from shot to shot. So far I've found no solution. Has any one found something worth knowing about this?

    As of yet, there doesn't seem to be any answer to this most annoying problem. I'm up to 4.6.2 now and still have to move those damn sliders off of zero and back down on every image and actually WATCH it to know it's doing what i want - which is nothing.

    How hard would it be for Phase to add a checkbox in the output panel next to the one for sharpening, so no matter what the settings were in the NR panel, we could just leave it unchecked all the time.

    As it is right now, C1 is bordering on unusable, forcing me to several added steps for EACH image I process. If Phase can't fix this bug, then perhaps my "feature" request would be a reasonable alternative.

    Sadly, 4.7 has NOT fixed the luminance / sharpening defaults problem.

    Anyone who is experiencing this problem, please put in a support case if you haven't. The more voices the better.

    I updated to 4.7 and was disappointed to see the amount of noise reduction this version applies on its own. I shot photos of a band at ISO 1600, which I'd done previously, and had never noticed such a change in prior low light/high ISO shoots. The automatic NR in this version kicks-in about one second after C1 focuses the image. I also had problems trying to maintain a preset for NR. I've since downgraded to 4.5.2, which still applies automatic NR, but not to the extreme of 4.7. Version 4.5.2 also seems to respect presets.

    @Phase One: If you must include automatic noise reduction, PLEASE allow a selection in Preferences of either On or Off.

    Did you try to create a new default value for noise reduction in 4.7?

    Yes, I did set a new default NR profile in 4.7 with both Luminance and Color set to zero in the hope of minimizing the influence of the automatic noise reduction. C1 4.7 will hold that preset after I set the Luminance and Color sliders and select Reset Defaults.

    However, even with both sliders set to zero, C1 4.7 still applies its own automatic noise reduction. I re-installed version 4.5.2, and comparing the same photo between 4.5.2 and 4.7 (now running in trial mode), 4.7 does apply much more noise reduction than 4.5.2 at the presets of Luminance at 25 and Color at 55. The photo as displayed in 4.5.2 is sharp and useable; the same photo as displayed in 4.7 requires noise reduction adjustment due to being blurred. And again, this is using the identical presets of 25/55 on each version and with no other adjustments made to the photo.

    Do you base your evaluation of applied noise reduction on CO 4.5.2 versus 4.7 viewer display or on the output of both version to (for example) Photoshop? The latter would be correct, the previous evaluation not, due to differences of display in Capture One versions mentioned.

    The other issue is CO applying noise reduction while the slider is set to zero. Not being into that myself, I understand from other posters here that slightly increasing the value and returning to zero will effectively reduce noise reduction application. Have you been able to do that and than set a new default?

    I did view the image only on my computer display while it was open in both 4.5.2 and 4.7. when I wrote the last post.

    To compare the image as you suggested, I created an 8-bit TIFF of the image using both 4.5.2 and 4.7 with the noise reduction set to luminance 25 and color 55 in both C1 versions. No other adjustments were made to the image in either version. I then viewed both TIFF files using Apples Preview and GIMP. As you implied they would be, they were identical and did not display unusual noise reduction.

    Prior to using version 4.7 I never paid much attention to noise reduction adjustments because it was unnecessary, even for previous images I had taken under the same conditions. I did set two defaults in 4.7 for use with these images so the extreme noise reduction 4.7 applies is not so much of a distraction to me.

    The noise reduction sliders will effect the image regardless of whether they are first set to zero or some intermediate setting. A zero/zero setting, which is now one of my defaults, does seem to remove most of the 4.7 applied noise reduction.
